Dry blend for making extended cheese product

ABSTRACT

Disclosed herein are dry blends used in the process of making extended cheese products with improved meltability and firmness profiles.

This application is a continuation of U.S. patent application Ser. No. 13/873,607, filed Apr. 30, 2013, which claims the benefit of priority of U.S. Provisional Application No. 61/640,782, filed May 1, 2012, the disclosure of which is hereby incorporated by reference as if written herein in its entirety.

In recent years there has been a significant increase in demand for cheese generally, as well as for cheeses with specific performance or nutritional characteristics. This general demand is driven in part by the steady growth in the ready meal or convenience food sector of the food industry since cheese is an ingredient in many foods within this sector. The increasing popularity of various pizza-type products is one specific example of cheese-containing products in this sector that have contributed to the surge in demand. Consumer's health concerns have been a major factor driving the increased demand for cheeses with improved nutritional characteristics, such as those that are lower in fat, differ in fatty acid profile, have increased calcium content, and/or are lower in cholesterol. These concerns, as well as cost considerations, have been the impetus for the development of a number of cheese analogues (e.g., imitation cheeses or cheese substitutes) that offer various health advantages (e.g., replacement of animal fat with healthier vegetable oil and increased vitamin or mineral levels) and cost benefits (e.g., vegetable oils are less expensive than certain dairy ingredients).

Demand for cheese with varying performance characteristics is also driven in part by the significant increase in the different types of baking equipment and conditions that are being used to prepare food products containing cheese. Some baking operations, for instance, require relatively high oven temperatures (e.g., in the range of about 350 to 950° F.) with short baking times (e.g., in the range of about 30 seconds to 15 minutes). Such conditions may be used, for instance, in an impingement oven when baking a pizza having a thin crust. Other ovens, such as deck ovens, in contrast, sometimes use a relatively long bake time (e.g., about 6 to 60 minutes) and a correspondingly lower oven temperature (e.g., about 300 to 750° F.). Instead of baking, some foods topped with or including cheese are prepared by microwaving (e.g., about 1-6 minutes).

There are a variety of challenges to providing cheeses that have a composition which satisfies the desired performance characteristics and nutritional qualities. For instance, it can be difficult to obtain the desired concentration level of some ingredients in a cheese. Another problem is developing a process that activates the latent functional properties of certain ingredients. Another problem is that many methods for preparing cheese involve the loss of significant quantities of some cheese components during processing. This can occur, for instance, when such cheeses undergo the heating and stretching process of the pasta filata process. Often the heating is conducted in heated water, which can remove significant amounts of cheese ingredients.

In view of the high demand for cheese and the foregoing shortcomings associated with some existing methods for preparing such cheeses with the desired performance characteristics, there thus remains a need for additional methods for preparing cheeses of these types.

As alluded to above, there has been an increased demand for extended cheese products because of cost and health considerations. Extended cheese products generally refers to a cheese in which a filler has been added to extend the mass and volume of the cheese while maintaining the physical properties of the natural cheese. Extended cheese products are typically lower cost than other cheese types because the extending can be performed less expensively and because certain milk ingredients can be extended with cheaper products (e.g., extending milk fat with vegetable oil or milk protein with starch). The health benefits derive from extension of the milk fat and protein with other healthier ingredients and the ability to add other ingredients that can lower the cost of the final product.

Analogue cheeses constitute a major category of cheese. As alluded to above, there has been an increased demand for analogue cheese because of cost and health considerations. Analogue cheese generally refers to a cheese in which milk fat and/or a protein source has been substituted with a source that is not native to milk. Analogue cheeses are typically lower cost than other cheese types because the processing can be performed less expensively and because certain milk ingredients can be substituted with cheaper products (e.g., substituting vegetable oil for milk fat). The health benefits derive from substitution of the milk fat and protein with other healthier substitutes and the ability to add other ingredients that can improve the nutritional characteristics of the final product.

However, replacing a conventional cheese composition ingredient can present one or more technical hurdles because cheese compositions are complex compositions and their properties can be sensitive to (i.e., require) the presence and/or amount of certain ingredients. Thus, conventional cheese manufacturing has come to rely on certain cheese composition ingredients to provide certain properties. Exemplary technical challenges include finding a substitute ingredient that can provide a cheese composition with one or more suitable functional properties (e.g., melt, stretch, and firmness), organoleptic properties (e.g., texture and flavor), and nutritional properties.

Casein is one of the major components of cheese and typical extended cheese products. The more cheese that is used in the extended cheese product, the less casein is required from the other components of the product. This family of related phosphoproteins is commonly found in mammalian milk, making up 80% of the proteins in cow's milk. Over the last few years casein has dramatically increased in price. Accordingly, there is an ongoing need in the cheese industry for an extender for casein in the manufacture of extended cheese products. One such extender is whey. Whey can be used to reduce or eliminate the need for the use of casein in making extended cheese products.

Starch can also be used as an extender for milk protein, milk fat, and cheese in extended cheese products. However, the ability to extend casein protein with starch can be significantly limited depending on the desired functional, organoleptic, and/or nutritional properties of the cheese composition. For example, extending casein with starch can provide a cheese composition with less than desired functional properties (e.g., melt, stretch, and firmness) because starch is not necessarily always a “functional” replacement of casein protein, but can merely replace a certain mass of casein protein. Similarly, starch can impart a different, sometimes less desirable, flavor and/or texture to the cheese composition than provided by casein. Furthermore, replacing casein protein with starch, a carbohydrate, can significantly alter the nutritional characteristics of a cheese composition (e.g., the cheese composition may not satisfy nutritional standards imposed by the United States Department of Agriculture). Thus, conventional cheese making has come to rely on the mere presence and sometimes quantity of casein protein to provide certain cheese composition properties.

Despite these limitations, there exists a strong desire (e.g., economic incentives) to further reduce the amount of casein protein in certain cheese compositions. However, providing suitable functional, organoleptic, and nutritional characteristics while reducing the casein protein even further in certain cheese compositions presents significant technical challenges.

Another ingredient that is commonly found in cheese analogues is shortening, which often contains trans-fat. In general, recent consumer trends indicate that trans-fatty acids (i.e., “trans-fat”) in food products and food intermediates are being avoided by consumers to help increase the healthfulness of their diet. Accordingly, many food product marketers are finding ways to provide consumers with food products having reduced and/or substantially no trans-fat content.

Trans-fat is an unsaturated fatty acid in which the hydrogen atoms of a double bond (or unsaturation) are on opposite sides of the molecule. The trans isomer of the fatty acid causes the carbon chain to assume a straight-chain configuration similar to that of a saturated fat. Trans-fatty acids are primarily formed through the metal-catalyzed process of hydrogenation, however they have also been found to form naturally and is found at low levels in cow's milk. By hydrogenating oils through industrial processing, hydrogen atoms are added to unsaturated sites on fatty acids, creating a larger population of saturated fats in the oil. In a partially-hydrogenated oil, some of the unsaturated fatty acids remain. However, the processing causes some of the double-bonds of the unsaturated fatty acids to undergo isomerization from the cis configuration to the trans configuration.

Partial hydrogenation of fats was introduced into the U.S. food supply beginning in 1910. The practice was put into widespread use in the 1940's in order to make semisolid fat products. The process of hydrogenation raises the melting point of a fat and increases the solid fat content. Such fats having higher melting points and solid fat content help provide food compositions (e.g., cheese compositions) with highly desirable functional properties. For example, oils containing trans-fats can help an analogue cheese to have highly desirable properties (e.g., melt, crumble, stretch, firmness, combinations of these, and the like) at one or more temperatures (e.g., shred temperature, temperature of a consumer's mouth, combinations of these, and the like). In addition, the stability of the fat is greatly enhanced through hydrogenation by reducing susceptibility to oxidation and subsequent rancidity. Therefore, positive contributions to processing properties, shelf-life, texture, and taste of food products (e.g., cheese compositions and food products incorporating such cheese compositions) are imparted by hydrogenated and partially hydrogenated fats.

A recent consumer trend is to avoid consuming food products that are high in, or have an undue amount of, trans-fat. To help meet consumer demand many food manufacturers would like to provide consumers with food products (e.g., analogue cheeses and food products that include cheese (e.g., snack food (e.g., frozen snack food) including pizza, pizza-type snack food, and the like)) having a low amount of trans-fat (e.g., about 5% or less by weight of trans-fat based on the total weight of the fat component). However, changing the formulation of a food composition to accommodate this can present significant technical hurdle(s) because of the reliance specifically on trans-fat containing ingredients to provide one or more highly desirable properties in food products and food product intermediates. Changing the trans-fat content of a food product can significantly impact properties such as processing properties, organoleptic properties, combinations of these, and the like, of the food product. As mentioned above, analogue cheeses are complex chemical compositions, therefore their properties (e.g., melt, crumble, stretch, firmness, combinations of these, and the like) could be unduly affected by changes in formulation amounts and/or ingredient(s) that would affect trans-fat content. Accordingly, there is a strong need to provide analogue cheeses having a low amount of trans-fat (e.g., about 5% or less by weight of trans-fat based on the total weight of the fat component) while at the same time substantially maintaining and/or improving analogue cheese properties such as melt, crumble, stretch, firmness, combinations of these, and the like. In addition, there is a strong need to provide food product(s) including such analogue cheeses and methods of making such analogue cheeses and food products.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 depicts one example of a general method for making a cheese product using a dry blend.

DETAILED DESCRIPTION

A “cheese analogue” as used herein refers generally to a cheese in which at least one milk fat and/or protein source has been replaced with a source that is not native to milk. The basic ingredients for a cheese analogue are usually water, casein, a fat/oil and a sequestering agent. Cheese analogues are typically categorized as dairy (all fats and proteins come from dairy sources), partial dairy (some fats and proteins come from dairy sources, while other have been replaced with non-dairy fats and proteins), or nondairy (all fats and proteins come from non-dairy sources). They can also be classified as being an imitation cheese or a substitute cheese. Imitation cheese is a substitute for and resembles another cheese but is nutritionally inferior to that cheese. A cheese substitute, on the other hand, resembles another cheese but is not nutritionally inferior to that cheese.

An “extended cheese product” is a food product based on a natural cheese, but wherein filler material has been added to the natural cheese to extend the mass and volume while maintaining or improving the physical properties of the natural cheese (i.e. meltability, stretchability, browning, elasticity, free oil formation, etc.). Extended cheese products are a type of cheese analogue.

A “pre-filled cheese extender package” is a package containing the dry blend that includes all the ingredients needed for a user to create an extended cheese product, such as, but not limited to, starches, gums, acidulants, whey, casein, emulsifiers, salts, and gelatin. These ingredients have been homogenously blended before being packaged.

Processed cheese has several technical advantages over unprocessed cheese, including extended shelf-life, resistance to separation when cooked, and uniformity of product. Its production also enjoys significant economic advantages over traditional cheese-making processes, most often through the ability to incorporate any of a wide variety of less expensive ingredients.

Emulsifiers are used to provide a uniform structure during the melting process. The essential role of the emulsifying agents in the manufacturing of processed cheese is to supplement the emulsifying capability of cheese proteins. This is accomplished by removing calcium from the proteins; peptizing, solubilizing and dispersion of the proteins; hydrating and swelling of the proteins; emulsifying of fat and stabilizing of the emulsion and by forming an appropriate structure after cooling. The use of emulsifiers in processed cheese results in cheese that melts smoothly when cooked. With prolonged heating, unprocessed cheese will separate into a molten protein gel and liquid fat; processed cheese will not separate in this manner. The emulsifiers, typically alkaline sodium aluminum phosphate, disodium phosphate duohydrate and sodium citrate, or other sodium or potassium phosphate, tartrate, or citrate salts, reduce the tendency for tiny fat globules in the cheese to coalesce and pool on the surface of the molten cheese.

A number of different types of starches can be incorporated into the dry blend. Suitable starches include vegetable starches (e.g., potato starch, arrowroot starch, pea starch, and tapioca) and grain starches (e.g., corn starch, wheat starch, and rice starch). Specific examples of suitable corn starches include dent corn starch, waxy corn or maize starch, and high amylose corn starch. The starches can be used individually or in combination. As noted above, starches can advantageously be included in the slurry. In some applications, the starch is added as a powder or unheated solution.

The starch can be modified or native. Modified starches, also called starch derivatives, are prepared by physically, enzymatically, or chemically treating native starch, thereby changing the properties of the starch. Modified starches are used in practically all starch applications, such as in food products as a thickening agent, stabilizer or emulsifier. Modified food starches differ in their degree of cross-linking, type of chemical replacement, oxidation level, degree of molecular scission, and ratio of amylose to amylopectin.

Examples of suitable gums that can be incorporated include, but are not limited to, xanthan gum, guar gum, konjac flour and locust bean gum. Examples of suitable stabilizers include chondrus extract (carrageenan), pectin, gelatin, and agar. Their synergistic interaction improves the textural quality of foods. It imparts rich mouth feel without masking flavor, enhances moisture retention, prevents syneresis and ice crystal formation in frozen products and forms thermally reversible gels. Blends of Xanthan Gum, Locust Bean Gum and Guar Gum are commonly used in the production of extended cheese products.

Acidulants are additives that give a sharp taste to foods by increasing the tartness or acidity. They also assist in the setting of gels and to act as preservatives. An acidulant (acidic agent) can be incorporated to adjust the pH of the finished cheese to a desired level. The acidity of the cheese can be controlled to help regulate the melt down characteristics of the finished cheese. Various acids can be employed; examples of suitable acids include, but are not limited to, acetic acid, citric acid, fumaric acid, lactic acid, malic acid, phosphoric acid, tartaric acid adipic acid, hydrochloric acid, glucano delta lactone, lactobionic acid or Genlac C, the latter being a blend of water, citric acid, lactic acid, acetic acid and artificial flavors. Acid is typically added to adjust the pH of the finished cheese to a pH from about 5-6 is reached, and more typically from pH 5.10-5.90.

A colorant can be incorporated into the soft or firm/semi-hard ripened or unripened blended cheese to adjust its natural color. This can be useful, for example, if consumers have a preference for a color other than the naturally-occurring color. Examples of suitable colorants include annatto, turmeric, titanium dioxide, and beta-carotene. Colorants may be of both the natural or artificial color. If one wished to color the cheese a red, an artificial color such as FD&C red #40 can be used. Annatto imparts a yellowish color to cheese. The yellowish color often is preferred by consumers who perceive it to indicate a “richer” product upon cooking on a pizza. Colorants can be incorporated into the final soft or firm/semi-hard ripened or unripened blended cheese product by inclusion in the slurry. If added at the mixing stage, the colorant is generally sprayed onto the heated cheese mass as an unheated solution or dispersion in water. The amount of colorant added is typically in the range of about 0.01 to 0.02%, based on the weight of the finished cheese. Turmeric, if used, is generally added in an amount of about 0.01 to 0.001%. If annatto is added, it normally is added to about 0.1 to 0.2% by weight.

Various flavoring agents can also be incorporated into the cheese to tailor the flavor profile of the cheese to meet consumer preferences. Suitable flavors for mixing into the heated cheese include, for example, natural mozzarella flavor such as diacetyl and/or lipolyzed fat, or enzyme modified cheese for cheddar cheese. Flavoring agents can be incorporated into the final soft or firm/semi-hard ripened or unripened blended cheese product by incorporation into the heated slurry or by addition to the heated cheese mass as a dry powder, or more typically as part of an unheated aqueous solution. Flavoring agents are typically added in an amount such that the concentration in the final cheese product is within the range of about 0.01 to 5 wt. %. If incorporated into the slurry, the concentration of the flavoring agent in the slurry is generally is in the range of about 0.11-4.50 wt. %.

Non-dairy fat refers to various vegetable fats. These fats may be partially or fully hydrogenated, yielding a cheese product that is low in trans-fat. In an embodiment, the fat has a melting point close to that of butter fat, 93-103° F. Further, the fat may be blended with a liquid fat (oil) during the cheese making process.

Whey is the liquid remaining after milk has been curdled and strained. It is a by-product of the manufacture of cheese or casein and has several commercial uses. Sweet whey is manufactured during the making of rennet types of hard cheese like mozzarella, cheddar or Swiss cheese.

Cheese curds are an important step in the cheese making process. They are small chunks of cheese solids which have been separated from the natural whey present in milk, but not yet pressed into molds to make cheese. Different treatments of the curds yield different end cheeses, and the curds can also be eaten straight. The curdling process coagulates the solids in the milk, yielding cheese curds swimming in whey. The whey is drained from the curds, which may also be cut to facilitate drainage, and then the cheese curds can be salted, packed into molds, and turned into cheese.

Casein is the name for a family of related phosphoproteins (αS1, αS2, β, κ). These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow milk and between 20% and 45% of the proteins in human milk. Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive, to a binder for safety matches. As a food source, casein supplies amino acids; carbohydrates; and two inorganic elements, calcium and phosphorus. Casein contains a fairly high number of proline residues, which do not interact. There are also no disulfide bridges. As a result, it has relatively little tertiary structure. It is relatively hydrophobic, making it poorly soluble in water. It is found in milk as a suspension of particles called “casein micelles” which show only limited resemblance with surfactant-type micellae in a sense that the hydrophilic parts reside at the surface and they are spherical. However, in sharp contrast to surfactant micelles, the interior of a casein micelle is highly hydrated. The caseins in the micelles are held together by calcium ions and hydrophobic interactions. Types of casein commonly used in cheese making comprise, but are not limited to, rennet casein, acid casein, calcium caseinate, sodium caseinate, and potassium caseinate.

Dry blend refers to the “dry” (i.e. less than 15% water) starting material one would use in make of extended cheese product. A dry blend is a homogenous mixture of the ingredients that may be sold as a pre-packaged mix to a cheese manufacturer or user. Normally water and some type of fat would be added to produce the extended cheese product. One could also add in a desired flavor to resemble the desired cheese taste.

The dry blend that is provide here for use in the extended cheese product is designed to improve: 1) melt and flow ability of the final cheese product, which is a measure of how well the cheese melts and flows into a homogenous mass, preferably with little or no individual shreds of cheese still detectable; 2) stretch, which is measure of the ability of the cheese to form interconnected strings when the heated cheese is pulled; 3) texture, which is a measure of chewiness and smoothness; 4) coloring, which is a measure of the actual color of the melted cheese; 5) blister characteristics, which may include size, color and extent of coverage; and/or 6) nutritional composition.

The dry blends described herein are manufactured it in one step by blending all the dry material contained in the formulas described herein in a double ribbon blender. These batches are blended during addition of the ingredients, and then blended an additional 10 minutes, or until a homogenous mixture is obtained, after all ingredients have been added. Optionally, a food grade oil can be sprayed on with the blender running, with an additional 10 minutes of blending, or until a homogenous mixture is obtained. The dry product obtained at the conclusion of the blending is packed and is ready to be packaged or used in the cheese making process.

Melt the fat (milk or vegetable fat) and then add the dry blend, optionally add flavoring, and then add water, in that order, and blend for 5 minutes. Cook the mixture to about 150° F. Add cheese and/or cheese curd and cook the resulting mixture to 160° F.-175° F. Form the extended cheese product and cool it. The extended cheese product can then be packaged and refrigerated. Once cool, the product may be shredded or sliced, if desired. The amount of natural cheese product used may vary, such as at least 45%, depending the on the desired product.

Alternatively, melt the fat (milk or vegetable fat) and then add the dry blend, optionally add flavoring, add approximately two-thirds of the water, then the cheese and/or cheese curds, and optionally, casein, and blend for 1 minute. Cook the mixture to 150° F.-155° F. Add the remainder of the water and the acidulant and mix for 1 minute. Cook the resulting mixture to 160° F.-170° F. Form the extended cheese product and cool it. The extended cheese product can then be packaged and refrigerated. Once cool, the product may be shredded or sliced, if desired. The amount of natural cheese product used may vary, such as at least 45%, depending the on the desired product.

Meltability is measured by cutting a disk of cheese of a specified size, and placing the disk in a glass Petri dish. A technician heats the Petri dish in an oven at an elevated temperature for a specified time (350° F. for seven minutes), then pulls the dish out and measures the diameter of the circle the melted cheese has formed.

Stretchability of cheese can be determined by adapting a texture-profile analyzer to pull strands of cheese upwards from a reservoir of melted cheese. Cheese is placed into a stainless steel cup and tempered in a water bath at varying elevated temperatures, such as 60, 70, 80, or 90° C., for a specified time period, such as 30 min, before analysis. The cup is then placed in a water-jacketed holder mounted on the base of the instrument. A three-pronged hook-shaped probe is lowered into the melted cheese and then pulled vertically until all cheese strands break or 30 cm is reached. This produces a stretch profile as the probe is lifted through the reservoir of melted cheese and then pulls strands of cheese upwards. An additional test for measuring the stretchability of cheese was developed by heating a specified amount of cheese on a thermostatically controlled hot plate, followed by measuring the distance between the hot plate and moveable stretching plate before the cheese strands are torn off.

Further, a subjective test for meltability and stretchability may be performed. The cheese is shredded and a predetermined amount, such as about 200 g, is placed on top of a pizza crust covered in pizza sauce. The resulting pizza is baked in an over, such as for 4-9 minutes at 500° F. The pizza is removed from the oven and allowed to cool, such as for 1 minute. A visual check is then performed to determine if the cheese melted. If so, the melting is checked for homogeneity of the melt and spreading. The melted cheese is stretched and subjective determinations about the stretchability can be made, such as long stretches and weak stretchability.

The above dry blends will provide an ingredient to be used in making extended cheese products with improved melting and stretching properties.
